Arp 278 (Gary Imm)

Celestial hemisphere: Northern · Constellation: Pegasus (Peg) · Contains: NGC 7253

Arp 278

This object, also known as NGC 7253, is a pair of interacting galaxies located 210 million light years away in the constellation of Pegasus at a declination of +29 degrees. In his Arp catalog, Dr. Arp classified this object into the category of Double Galaxies - Interacting.

Each galaxy spans about 1.5 arc-minutes in our apparent view, which corresponds to a diameter of 90,000 light years. The 2 galaxies are clearly interacting, with a stellar bridge spanning between them.

These 2 galaxies look so similar that they seem like twins. Both have a similar length and thickness, with clearly defined meandering dust lanes throughout. The inner section of both disks is fairly intact and undisturbed, but the outer portions of both disks are heavily disturbed.

Numerous bright and colorful stars dot the foreground in this portion of the Milky Way.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
